Eventually he accepted that I could see anther consultant to get a second opinion, but then proceeded to tell me that if I did get an ELCS he would write all over my notes that if I went into early labour (i.e. before date of booked section) I was not to get a section.
Firstly, it is unethical and against doctors code of conduct to issue threats in order to 'persuade' you to behaviour a particular way and to bully you out of pursuing a particular type of treatment. If you have been told this, you should make an official complaint.
With respect he can write this on your notes, and it does not mean shit unless he also bullies staff. In which case you have a hospital where there is systematic and institutionalised bullying which is..., well its a recipe for wider problems.
I would be pointing out BOTH in any complaint made. Get it on the official record as it removes the issue of systematic institutional issues as any doctor intimidated by this jerk off will be given power by it and be more able to use their own professional judgement to ignore him as they are within their rights to do.
The 'can't or won't' comment is also at odds with ethics and is unacceptable. Under the NHS you have a right to be treated with respect and dignity. By saying this, he is not and is behaving in a bullying manner. It is also at odds with the research about why women ask for CS. And the NICE guidelines.
I would be asking the hospital to comment on the research available for too posh to push verses mental health reasons stemming from abuse in childhood and whether they consider his manner appropriate. He is actually risking causing harm to a vulnerable person by being dismissive and aggressive in his manner. Again this is against his oath to the NHS as a doctor.
That's three separate real issues in his conduct.
I would be also taking steps to seek out mental health support a) you say its ruining your whole life at the moment so you NEED it and b) it backs up your request for a CS and c) puts this doctor in a position where he is at risk of being show up as being a damaging force and contributing factor to damage to your mental health.
I would make sure you have this all written down for ANY and ALL future meetings relating to your health or the complaint itself.
Use official sources to quote from - eg what NICE says and what the GMC ethics code is. Its about throwing the book at them.
The fact this consultant face disciplinary action over his manner is separate from your request for a CS. PLEASE PLEASE bare this in mind. He can write all over your notes, but it can be over ruled at any time and they really have little weight.
